Flow rate is one of the main factors affecting cartridge filter housing selection. Lower-flow applications may use a single-cartridge housing, while higher-flow systems generally require more filtration area through multiple cartridges or a suitable high-flow configuration. The final choice also depends on fluid properties, filtration requirements, allowable pressure drop, and operating conditions.
Flow rate determines how much liquid must pass through the filtration system over a given period of time.
A cartridge filter housing must provide enough effective filtration area to handle the required process flow without creating excessive pressure drop or placing unnecessary load on the filter elements.
For this reason, flow rate is usually considered together with the cartridge type, cartridge length, filtration rating, and number of cartridges.
The goal is not simply to choose the largest housing. The housing and cartridge configuration should match the actual process conditions.
The required flow rate is one of the factors that helps determine whether a single-cartridge or multi-cartridge housing is appropriate.
• Lower-flow applications
A single cartridge housing can be suitable for lower-flow systems, pilot equipment, small production lines, and applications where compact installation and simple cartridge replacement are important.
YUBO single cartridge filter housings are available for 10", 20", 30", and 40" cartridges and can be configured with SS304 or SS316L construction.
• Higher-flow applications
When process flow increases, one cartridge may not provide sufficient filtration area. A multi-cartridge housing allows several cartridges to operate in parallel, increasing the available filtration area within one housing.
YUBO multi-cartridge housings can be configured with different cartridge quantities and lengths according to the application.
This makes multi-cartridge filtration suitable for larger industrial water treatment, chemical processing, and other continuous liquid filtration systems.
How Does Flow Rate Affect Cartridge Quantity?
Cartridge quantity is closely related to the required flow rate, but it cannot be determined from flow rate alone.
The cartridge manufacturer's flow and pressure-drop data should be considered together with the process fluid and required filtration rating.
For the same housing size, changing the cartridge media or micron rating can change the suitable operating flow.
In general:
Higher flow → more required filtration area → more cartridges or a different cartridge configuration
Additional filtration area can be provided by:
• Increasing the cartridge quantity
• Using longer cartridges
• Selecting a cartridge with greater effective filtration area
• Considering a suitable high-flow cartridge configuration
The final configuration should also provide appropriate flow distribution through the housing.
A cartridge housing should never be selected based on flow rate alone.
Other important factors include:
• Filtration rating: A finer filtration requirement may create greater flow resistance and can affect cartridge selection.
• Fluid properties: Viscosity, temperature, and chemical characteristics influence filtration performance and pressure drop.
• Contaminant loading: A fluid containing a high concentration of suspended solids may require greater filtration area or a suitable pre-filtration stage.
• Operating pressure and temperature: The housing must be suitable for the actual operating conditions.
• Allowable pressure drop: The selected cartridge and housing should provide the required flow without exceeding the acceptable pressure loss for the process.
This is why cartridge filter elements and housings should be selected as one filtration system rather than as completely independent components.
Consider high-flow configurations when the process requires a relatively large flow capacity but the user wants to reduce the number of conventional cartridges or simplify the overall filtration arrangement.
However, high-flow filtration is not simply a matter of increasing the flow through a standard cartridge.
The cartridge design, filtration area, housing structure, connections, and internal flow distribution must all match the required operating conditions.
For larger industrial water treatment and RO pre-filtration systems, YUBO can configure cartridge housings for standard or high-flow cartridge applications according to project requirements.
When requesting a cartridge filter housing, providing the following information helps the manufacturer determine a suitable configuration:
• Required flow rate
• Process fluid
• Required filtration micron rating
• Operating pressure
• Operating temperature
• Expected contaminant loading
• Cartridge type, if already selected
• Cartridge length, if known
• Connection requirements
• Available installation space
If the cartridge has not yet been selected, the manufacturer can evaluate the cartridge and housing together.
Flow rate is one of the main factors affecting cartridge filter housing selection. It influences the required filtration area and can affect cartridge quantity, housing configuration, and pressure drop.
Lower-flow applications may use a single-cartridge housing, while higher-flow systems may require multiple cartridges or a suitable high-flow configuration. The final selection should also consider filtration rating, fluid properties, contaminant loading, pressure, temperature, and allowable pressure drop.
YUBO supplies SS304 and SS316L cartridge filter housings in single, multi-cartridge, and security configurations. Cartridge quantity, length, connections, seals, and other specifications can be customized according to application requirements.
